[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides an umbrella-type folding photovoltaic mechanism capable of tracking light, characterized in that it includes a foldable solar panel group 1, a bracket 3, a tripod base 4, a pitch adjustment motor 6 and a panel group opening and closing control structure; the solar panel group 1 includes a plurality of photovoltaic panels 11 of a triangular structure, each photovoltaic panel is rotatably connected to an adjacent photovoltaic panel, and the edges connected to the adjacent photovoltaic panels correspond to each other;

[0041] The bracket 3 is fixed on the tripod base 4, the solar panel group 1 is hinged at one end of the bracket 3 away from the tripod base 4, the pitch adjustment motor 6 and the panel group opening and closing control structure are both fixed on the bracket 3, the panel group opening and closing control structure drives and connects the solar panel group 1, and is used to control the opening and closing of the foldable solar panel group 1, and the pitch adjustment motor 6 is connected to the solar panel group 1, and is used to adjust the direction of the upper end surface of the solar panel group 1.

[0042] Working principle: Place the photovoltaic mechanism of the tripod base 4 on the ground, then use the panel group opening and closing control structure to open the solar panel group 1, and the pitch adjustment motor 6 to adjust the angle of the flattened solar panel group 1 so that the front of the solar panel group 1 faces the sun, and adjust the incident angle of sunlight to convert solar energy. During use, when encountering bad weather or needing to be transferred, the panel group opening and closing control structure will fold the unfolded solar panel group 1, and the tripod base 4 can be folded for transfer.

[0043] By setting a foldable solar panel group 1, and cooperating with the panel group opening and closing control structure to drive and control the unfolding and folding state of the solar panel group 1, when the solar panel group 1 is unfolded, photoelectric conversion can be performed, and the angle of the solar panel group 1 is adjusted by the pitch adjustment motor 6, so that the upper end surface of the solar panel group 1 is always facing the sun, optimizing the incident angle of sunlight, maximizing the reception of solar energy, and improving the efficiency of electric energy conversion. When not in use, the solar panel group 1 can be directly folded up through the panel group opening and closing control structure action, saving space, reducing damage in bad weather, and effectively extending the service life of the device.

[0044] like Figure 5 As shown, the solar panel group 1 includes a folding unit 12 and a non-folding unit 13, and the folding unit 12 and the non-folding unit 13 are diamond structures of the same shape; the bottom edges of the two photovoltaic panels 11 are hinged to form the folding unit 12, and the bottom edges of the two photovoltaic panels 11 are connected to form the non-folding unit 13.

[0045] The two photovoltaic panels 11 of the folding unit 12 are connected by a hinge 2. The solar panels are fixed in pairs by the hinge, so that the panel group can be rotated and folded. At the same time, the hinge is set to be unable to rotate in the reverse direction, so as to ensure that the panel group will not reverse.

[0046] Further, the folding unit 12 includes an active folding unit 121 and a passive folding unit 122, and the hinge of the active folding unit 121 can be rotatably fixed to an end of the bracket 3 away from the tripod base 4;

[0047] The four ends of the active folding unit 121 are respectively hinged to four driven folding units 122, and the non-folding unit 13 is respectively connected to two driven folding units 122, and is symmetrically distributed on both sides of the hinge of the active folding unit 121;

[0048] After the solar panel group 1 is unfolded, the hinged bottom edge of the photovoltaic panel in the driven folding unit 122, the hinged bottom edge of the photovoltaic panel in the active folding unit 121 and the connecting bottom edge of the photovoltaic panel in the unfolding unit 13 are parallel to each other.

[0049] like Figure 5 and Figure 6As shown, the opening and closing control structure of the solar panel group drives the active folding unit and the non-folding unit to move. The active folding unit folds downward, and the non-folding unit folds upward, and the driven folding unit between the two is folded and closed. The overall size of the solar panel group is consistent with the diamond structure of the non-folding unit. After folding, it occupies less space, is lighter in weight, and is more convenient to carry.

[0050] Specifically, Figure 3 As shown, the plate group opening and closing control structure includes a connecting rod 5, a slider 7, an opening and closing control motor 8, a steel wire connecting rope 9, a first opening and closing arm 14 and a second opening and closing arm 15;

[0051] A first section of the opening and closing arm 14 is fixed to the lower end of the active folding unit 121, and a second section of the opening and closing arm 15 is fixed to the lower end of the non-folding unit 13. One end of the first section of the opening and closing arm 14 is hinged to the bracket 3, and the other end is hinged to the second section of the opening and closing arm 15;

[0052] The slider 7 is sleeved on the bracket 3, and the opening and closing control motor 8 is fixed on the bracket 3. The output end of the opening and closing control motor 8 drives the connected slider 7 to drive the slider 7 to move along the bracket 3. One end of the connecting rod 5 is hinged to the slider 7, and the other end is hinged to a section of the opening and closing arm 14. One end of the steel wire connecting rope 9 is hinged to the connecting rod 5, and the other end is hinged to the secondary opening and closing arm 15, which is used to drive the non-folding unit 13 to rotate in the direction opposite to the rotation direction of the active folding unit 121.

[0053] In order to avoid possible interference of the slider during the upward push, the length of the connecting rod is specially calculated so that the slider cannot hit the motor that controls the pitch angle when it is pushed to the highest point. At the same time, a thrust stop is set at the highest point to prevent the slider from moving upward excessively. The length and strength of the connecting rod are determined according to the size of the solar panel group, and the solar panel group and the slider are connected by a hinge to transmit the power from the slider, thereby realizing the unfolding and folding of the solar panel group.

[0054] The panel group opening and closing control structure has two connecting rods, including a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the photovoltaic panel on one side of the active folding unit 121, and the other end is hinged to the slider 7. One end of the second connecting rod is hinged to the photovoltaic panel on the other side of the active folding unit 121, and the other end is hinged to the slider 7. The first connecting rod and the second connecting rod are symmetrically arranged on both sides of the slider 7.

[0055] The secondary opening and closing arm 15 and the connecting rod 5 are kept parallel to each other, and a quadrilateral structure is formed by the steel wire connecting rope 9, so that the secondary opening and closing arm 15 can move according to the movement of the connecting rod 5.

[0056] like Figure 4 As shown, the output end of the pitch adjustment motor 6 is hinged to the photovoltaic panel of the active folding unit 121 to drive the solar panel group 1 to rotate around the upper end of the bracket 3.

[0057] The pitch adjustment motor 6 is connected to a control unit, which obtains the corresponding sunlight angle according to the position information of the photovoltaic mechanism and controls the pitch adjustment motor 6 to adjust the angle of the solar panel group 1. The movement of the electric push rod of the pitch adjustment motor 6 can be controlled by a controller, and the controller controls the required rotation angle of the motor according to the signal input by the photoelectric sensor.

[0058] Specifically, the photovoltaic panel is an isosceles triangle structure. The tripod base 4 includes a transverse fixing rod, one end of which is connected to the fixing foot of the tripod base 4, and the other end is connected to the bracket 3. The tripod base is fixedly placed on the ground, and whether to use fasteners to fix it to the ground is determined according to the usage scenario. If it needs to be frequently carried, it does not need to be fixed. Three transverse fixing rods are used in the tripod base to increase the stability of the base.

[0059] In combination with the above preferred embodiment, when installing the photovoltaic mechanism of this embodiment, the bottom of the bracket 3 is connected to the tripod base 4 with screws. The solar panel groups are connected in pairs through hinges. The hinge position must ensure the correct rotation direction of the solar panel group. There is a hinge at the midpoint of the center hinge 2, which is connected to the top of the pillar. Then, the pitch adjustment motor 6 and the opening and closing control motor 8 are fixed to the pillar with screws, and the pitch adjustment motor 6 is on the upper side. The slider 7 is put on the bracket 3 and connected to the top of the opening and closing control motor 8. Then, the connecting rod 5 is connected to the slider 7 and the solar panel group 1 respectively with hinges, and the top of the pitch adjustment motor 6 is connected to the solar panel group 1 by a hinge; the installation process is completed.

[0060] Before use, please note that there should be no obstacles that interfere with the rotation within 2000mm with the bracket 3 as the center, otherwise it is easy to cause unnecessary property losses, including but not limited to the damage of obstacles, the damage of the solar panel group 1, the damage of the opening and closing control motor 8, etc.

[0061] Specifically, the device is completely driven by a motor. It should be noted that during normal use, the solar panel group 1 cannot be forcibly opened or closed or the pitch angle cannot be changed by human power. Among them, the pitch control motor 6 controls the pitch angle of the entire structure, always keeping the height facing the sun to obtain a larger illumination area; the opening and closing control motor 8 controls the opening and closing angle change of the connecting rod by driving the slider 7, further expanding or closing the structure.

[0062] Furthermore, when the device is in automatic working state, the pitch angle changes from small to large and then to small. After sunset, it is folded up and the pitch angle is reset to zero, waiting for the sunrise of the next day. The sunrise and sunset time of each year and the sunlight angle of each day can be automatically generated according to the position information through special software and imported into the control system to ensure long-term automatic operation.

[0063] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
